Epimeria rubrieques

…is a large species of amphipod that is native to the waters of the eastern Antarctic Ocean. E.rubrieques is an opportunistic feeder and has been observed both scavenging and showcasing predatory behavior. It has been mostly observed on surfaces but is is known to be a motile epibenthic swimmer as well (meaning it rarely swims).This species was recently discovered and much of its biology and ecology still remains unknown.

“Red Bull”(Acanthonotozoma inflatum)

Is a species of iphimediid amphipod that is found throughout the Arctic, North Atlantic, and Pacific oceans. Noted for its unique red coloration that earned it its name this amphipod is usually found in red algae, using its coloration as camouflage. However, the “red bull’s” diet consists mostly of bryozoans, instead of the algae it rests on.

“White Knight” (Acanthotozoma cristatum)

…a species of imphimediid amphipod that is distributed throughout arctic and European waters. Like the closely related “Red Bull” (A.inflatum) the white knight probably feeds mostly on bryozoans and spends its time resting on algae/coral.
